Swordfish is one of Environmental Defense’s worst seafood choices because of mercury content and the eco-unfriendly way it’s caught.

That said, here’s a caveat on halibut: Pacific halibut is one of Environmental Defense’s eco-best choices, but Atlantic halibut makes the eco-worst list.

So, how do you know what’s safe to buy?

As a health-conscious organic consumer, please take the time to read our article, Which Fish Is Fit to Eat?—an excellent overview of environmental pollution, sustainability, mercury content and other heath risks.
